Application f'lcfi December 31, 1904. Serial Blo- 239,113.

ol {.nnruhn have invented certain new and. nseconlnnnj'ing;r drawings, in which Figure 1 is e. plan View of e. single rnil with the trend portion broken ewnj' tobetter show tho chair or beso part of the rail; Fig. Q, a transverse section of the rail complete; engl Fig'. 2).. n persj'iective View with the tread portion in section. showing more particularly the manner ol' joining' the ends` ol the chair or brise sections.

'l`he object oi' this inventionis to provide a compound rnil which shell be exceedingly siniple in construction, inexpensive to nxnnnt'ecture :1nd easily nsseinbled, ns weil ns verydnrnhle, and which also shell provide for effectively brenking' the joints between the sections without employing fish-plates et the joints, ns

fully hereinafter set forth."

To the accomplishment olE this object and such others :is may hereinafter appear the invention consists oi' the parts and combination o'r' parts hereinafter fully described, and perticulnrlj' pointed out in the appended Claim,

reference beinghad to the accompanying'v d rnwings, rori'ning a port of this specification, in which the saine reference characters designnto like ports th roneghout the several views.

Referring to the drawing 'oy letters, rt designates the trend-section, the upper or wheelhenrine pnrt of which is constructed on the m'dinnrY lines, bot whose depending web poriion f is slightly tapered toward its lower end. lhc chnir or bese oiy the rail-is provided with the usnnl interni spike-iinnges.c and with e parir oi' n{werd-extendinghannes or plates/Z, extending the fnll length ot' the reil and forin- ,ing n groove or recess into which the llnnge.

ot' the trend-section nicely lits. The upper' edges of the linnges l iit in grooves in the under sido ol: the tree lsection. ln this way n compound rail is formed which shzill be much ensier nnd cheaper to manufacture than the or- :linnrjfsolid T-rnil and which will be stronger than thosnme.

rl"he 'trend-section in assembling the rail pnrlsis nrrnnned to span or breuk thc joints olI the clntir-sections, es shown in llig. l, and the choir-sections nre ..oned

section.

in the jiu-onlinr l the invention nre possible, end i manner shown. Each end @teach chair-seotionl is cnt bock or notched rertically, so that vone half ot its end well is forward ofthe other .inlf ff', and these parts of the end woll are connected by a longitudinal wall c2, so that' when the sections are joined they will orerlap, the transverse lines of the joint extending inward from opposite sides in different verti-V col planes to the center of the chair-section and being connected by n central longitudinal joint coincident with the shutting wells e2. The tread-section spans this joint, as shown in Fig.' 1, and the connecting-bolts ere passed through openings formed in the projectingn parts Z/ of the @heir-section, well es through the intermediate web or tiring@ 7; ofthe treedin this we); e very solid joint is made which will require no lish-pletes to keep the sections of the chair pnrt in elinement, the 'extensions n serving etlectnnlly ss fishplates.

A rail constructed in the manner set forth possesses important advantages over the coinmon solid rnil, some ol' which ero ns follows; The trend-Section may be reversed when it becomes cracked or slixjored along' one edge, thus contributing materially tothe lile oi the rail. Should thc'trcnd-section become crooked, it cannot be displaced 'from the interi ckingr flanges, thereby reducing the danger of eccident to a minimum. The rail will be exceedingly strong', it heilig milde op practiceliy of n. series of plates set on odge. Fislnplntes et the joints ere rendered unnecessary, thereby greatly reducing the cost ot' laying thc rnil und increasing its safety. ivlnde up in the manner described the rnii is much ensier to bend, and the bendingmay therefore be done et the point where thc rziil is laid.

Another feature lies in the t'nct that nil the sections are Closely inter-locked nndmutnnlly strengthened, thereby xneking the rnii prneticnlly continuous, doing nwey with thonsnnl objectionable joints, and distributing the weight of the trein long` distances nhend and to the rear. As will be seen, n worn-ont treed portion et any point :dongv the track may he readily removed and replaced by n new secn tion withoutdisturbing` the chair end without stopping trniic. Costly bonding is done ewny with, es it is simply necessary; to ley the bondwires across the abutting joints ol the chairsoctions in the groove therein.

'it will be appel-ent to those skilled in 'the nrt that Various mechanica-l embodiments ot' therellrnc do IIO noi'J wish to be limited to tbe exact arrange ment and construction shown.

what i oinirn, and desire to secure by Lettere Patent, is# 1 l inve Compound continuous rail, e series of soid one-piece chair-sections provided with a peif'of upward-extending seperated finnges, 'Jne nbutingends of said sections being` notch ed und inizerioeried, nach joint comprising end rfni e e' and e @entrai ongitudinai Well e runjninggf between tbe upward-extending ianges so 'es to form projecting parte d which serve as Sieb-platee, these projecting parts being provided with bolt-holes, and a, series of one-piece tread 1 sections having a' central depending izmge or web fitting in'and extending to the l bottom o the groove formed between the upward-extending anges of the chair-sections, substantially as described.

in testimony whereof I hereunto aix my Signature, in the presence of two \vit,nesses,tbis 19th day of December, 1904.
